tion stated motion is transmitted from the same to the hammer B by means presently described.

a is a rock-shaft having an arm I), on which is a lateral pin a. The said pin 0 is normally held against downward movement by a ledge d on an armature 6 when the said armature is attracted to and held against its complementary electromagnets f, which are designed to be arranged in a normally closed fire-alarm circuit, and hence it will be noted that so long as the said circuit remains closed the shaft a will be held against rocking; When, however, the circuit in which the I magnets f are arranged is broken and the said magnets are deenerglzed, the armature e is moved away from the magnets by a spring 6 or other means and the pin 0 is released from the ledge This enables a weight g on the'shaft a and acoiled spring 9 connected with the arm I),

I to forcibly rotate the said shaft a in the direction indicated by the arrow thereon in Fig. 2.

By reference to Fig. 7 it will be observed that when the shaft a is rocked in the direction indicated 'by"arrow in Figs. 2 and 7 a dog 3 thereon raisesan arm4, which trips a catch 5, pressed by a spring 6, and permits the said catch wfiy'u This allows the arms 7 and 8 to move with shaft 9 in the directions indicated by arrows and the arm 5 to move downwardly, s'aidarm 5 .being connected, through a rod 9*, with the'arm 1O of the hammer B. After the catch 5 flies upward the gravitation of the-weight J ulling on they drum F rotates the, pallet-whee G in the direction indicated by arrow, when said wheel acting first against one and-then against theotherof the pallets v 11 and 12rbcks the arm 5 down and up. At

the end of-each' pallet there is a lateral pin 13, which projects over 'a plate or guide 14, and at the end of eachinovement ofthe arm 5 thesaid guide 14 causes one of the pal-lets to pro erlyengage with a'tooth of the wheel G On the forward movement of the arm 7- a pin 7 b thereon engages an arm 15, fiired on the shaft a, with the result that the arm?) and pin 0 are returned to the position shown in Figs. 7 and 8 relative to, the armature e and the ledge d thereon,

ready for operation when there is another break in the circuit in which the magnets f i are" arranged. On the rearward movement of said arm 7 it slidesinto engagement with the catch 5 and enables the latter to hold the arm 4, which is then in the position shown in Fig.7. Said arm 4 is prevented from moving upwardly too far by the 16, disposed above it, as shown.

It will be apparent from the foregoing that when the circuit in which the magnets f are arranged is broken the hammer B will first be moved rearwardly to the position shown in Fig. 1 and then forwardly against the bell or other device A to be struck; also, that subsequent to each blow of the hammer B the parts fore mentioned the shaft a is provided with an arm h, the purpose of which will be presently set forth. i

L is a transverse shaft journaled in 'the frame or stand D and bearing a sprocket gear M; N, a clutch member loosely mounted and movable endwise on the shaft L and backed by a spring Nf P, a spur-pinion fixed' with respect'to the clutch member N;Q, a

spur-gear intermeshed with the pinion P; R,

a spur-pinion fixed with respect to the gear' Q and i'rite'rmeshed with the spur-gear I-l'on the shaft E';'S, an electromotor which per se may be of the ordinary construction or any other construction compatible with the purposes of my invention; T, a sprocket-belt connecting the gear M and the motor S, and U a clutch member complenfentary to the member P and fixed on the shaft L.

current is supplied to the motor S and the loose clutch member N is in engagement with the clutch member U, itwill be observed that" through the medium of the train of gearing .described the drum F will be rotated in the direction opposite to that indicated by the large arrow in Fig. 2, and hence theweight J will be raised. Incident to the eleivation of the weight J said weight is not adapted to actuate the hammer B, and from this it follows that in order to complete a fire-alarm the weight must be transferred"i. 12., connected to the hammerso that the gravitation of the weight will operate to actuate the hammer. This is accomplished through the medium of the shaft a, the arm 7!, of said shaft, a bell-crank lever V, fulcrumed on a bracket to, a cable X, connecting one arm of the said lever V, and the arm h of shaft a, a

lever Y, fulcrumed on the frame or stand D and having a yoke 11 and also having a rod 7', and a link 7c, connecting the arm of the lever V remote from the cable X and the lever Y. The yoke 11 of lever Y enga es the loose clutch member N, and hence it wi I be observed that when the neXt fire-alarm is sent in and the electromagnets f aredeenergized the shaft (1.

p'imeiiteiy ciutcilfmmbet iii will:

break the connection betwe n the electronmoton S and, the weight J, and hence will jen lab le theweightto gravitate andfby such gravitation forcibly impel the; hammer BL against the belljorether deviceA. I Irn'niedti; ately after the'shait aii's rockedby the weight g in the direction indicatedt the small at,-

row in Fig. 2. said shaft 'and-its appurtenances return .to their original gpos'iti'ons readyf or the next breaking o fthe fire-alarm, circuit, and.

hence eX'ert nopower to hold t'he clutchjmember N out of, engagement with, the, clutch,- member U. The finger 1', h wever, performs, this. latter function, for it will be 'se'enithat. by

reason of the saidfinger restingja't the right ofithe hammer B, Fig. 1, thelc'lutchm'emb'er Nfi's held away fromthe member U, with the result that the gravitation of the weight J 'is exerted on the hammer, B, until saidj'hammer 1 is 'moved'. against. the device A, when, the i111- ger-j is released, and-the spring Nfo'peratjes to during the soundingoi'an alarm-or until the ress the clutch member N against the memer 'U, and thereby 'reestabli'shes winding of" the-cable K on thedrum F andf'eleva'tionfof the Weight. J .4 Thisjoperatifon, is repeated weightis i its uppermost position, as shown in Fig. 1.

From this it v follows that during 1 the striking of an alarm the weight willj'befca'used-Tfto move, upwardly. This ism'aterially advantageous,jinasmuch as it assures the weight; always having sufficient fall to strike an alarm and renders .it unnecessary for the; traverse of the weight v to be of undue length. A' Fig. '3, is a source 'oifelectric"energy with one pole of which-the electromotor S is connectedf B" is 'a' post electrically 'connected withthe other pole of the source of electricenergy.

switch D has a handleE arranged "the petnef an" arm F on the weight'J, andthence",

when'the'said weight falls W and its arm F depresses the switch D ,soas t'o close. thepower circuit, the weightwill be'raisedfthrough the medium of "the "electror'no'tor S and the driv" ing connection'described; If'the weight 'J is thusra'isfed subsequentto 'thefirs't blow of an alarm, the powerof'jthleweight will he/transferredto the hammer B when the circuit on the. fire a larm wires is broken jfor the next blow through the medium of'the means be fOref described in detail.

I "Gis'jan' arm arrangedon theupper-portion ofthe weight J,'fand H is agc'zable passedbver asheave I""and connected atitsupper'endto I prefer practice "toein'p'loy' such a motor andarrange'ment of gears that intermediate the blows of the hammer B against. the device A the weight: will be raised about twice thedistan'ce it falls jtocause'each ,jblo'w, of the. hammer, agajnstthe device A,

raise the, lever D up out of engagement with the post B and will thereby break the powerci'rc'uit and'stop the 'elec'tromoto'r S and the parts connectedthere'with.

K Fig; 3 is an electric bell which is electhe switch-lever. On the neXt blow of the hammer B against the bell the weight Jwill drop and cause the switch-lever to make electric connection with the post B, and thereby complete the power-circuit and put 'said'cable H is arranged'to be engaged by i the arm G of the weight J when said weight reaches its uppermost position, as shown in 7b the motor S in motion, so as to raise said weight J. If, however, any part of the machine is out of; order and'the electromotor fails to raise the weight'J at the time stated, the weight in making another drop willfca'use the switch lever to move out ofengagement with the the shorter post This wil com lete the alarm-circuit, andiinging'oi the be l'K will apprise a person in authority that the automatic weight-raising mechanism is out of orderand'that it is incumbent on him to make post B and into engagement with use ofjthe crank M (shown in Fig. 1) and throughthe medium of the same raise the jweig ht by'ha'ndQ On the next blow of the hammer fB'the arm F will slip past the'handle E of the electric switch, and the weight J will continue to fall. This additional fall of the weight past the switch-lever D is pro vvided in'order that no matter what happens the'weight will travel downwardly a sufiicient distance to complete vthe sounding of an alarm transmitted through the. circuit in which. the electromagnets are arranged. When itis necessary to use the crank M the crank is intermeshed with the spur-gearfH.

1f preferred, the said crank might be permanently'mounted in the standard M and connected, as stated, with "the spur-gear H without interfei'ingwith the automatic operation ofithe; apparatus. I
